HTC thunderbolt flashing back to stock

Didn't know where to post this but may have found an easier way to flash a stock image on my tb. Hoping I didn't frig anything up so wanted another opinion. Downloaded the stock image for my tb the other night. Copied t to my root of my SD card and renamed it pg05IMG...whatever it is supposed to be named. Booted into hboot. It found the ' update' and I had made a android before hand so I excepted it and bam! Now I am unrooted and also showing Mecha with s-on in hboot.....everything seems to work. Any chance of damage? Was wondering earlier why the unroot process needed to push files such as busybox and misc.img through adb which is why I attempted this ..did I successfully bypass those steps? Anyone else want to give it a go for me?

Sent from the lightning capitol of my frigging hand!....oh yeah and the droidforums app!

Honestly though, I guarantee you that all the Devs will have a Gingerbread Custom ROM shortly before or after the official update is released anyway. The only reason I can think of to go back to unRooted is if you are selling or returning the phone. Or you just like the "safety blanket" of getting support from Verizon/HTC.
